Owner’s manual
Introduction
Thank you for choosing B&W.
Please read this manual fully before
unpacking and installing the product. It will
help you to optimise its performance.
The speaker is primarily intended for home
theatre installations, but is equally at home
with 2-channel audio. Separate sections in
the manual are devoted to the two
applications.
B&W maintains a network of dedicated
distributors in over 60 countries who will be
able to help you should you have any
problems your dealer cannot resolve.
Unpacking (figure 1)
Fold the carton flaps right back and
invert the carton and contents.
Lift the carton clear of the contents.
Remove the inner packing from the
product.
We suggest you retain the packing for
futureuse.
Check in the carton for:
4 self-adhesive rubber pads.
Positioning
All Applications
The speaker may be used in either vertical
or horizontal orientation. However, vertical
orientation offers better horizontal
dispersion and is to be preferred in most
cases as this leads to a more stable image
over a wide listening area.
Horizontal orientation can be used with little
detriment to the imaging if the speaker is
used in the front centre position of a home
theatre installation where the listeners are
within 15˚ of the centre line – equivalent to
0.8m at a listening distance of 3m.
The speaker has a reflex port at the rear.
Leave at least 10cm clear space between
the back of the speaker and the wall
behind, to allow the port to operate
properly.
Fix the 4 self-adhesive pads to the base of
the speaker. They give a degree of vibration
isolation, especially useful if placing the
speaker directly on top of a fairly flimsy
television. The flat area on top of the
television may be smaller than the base of
the speaker, so position the
feet accordingly.
Home Theatre (figure 2)
As a front centre speaker:
If using a projection television with an
acoustically transparent screen, place the
speaker behind the centre of the screen.
Otherwise position it directly above or
below the screen, whichever is closest to
ear level. Align the front of the speaker
approximately level with the screen.
As a front left and right speaker:
As an initial guide:
Make the height of the tweeter
approximately the same as the centre
speaker.
Space the speaker between 0.5m and
1m from the side of the screen.
As a surround speaker:
There are two ways of presenting surround
information. You can either attempt to get
good imaging in all directions or go for a
more diffuse, ambient effect. The choice is
made more difficult by the fact that some
movies are produced assuming a diffuse
surround presentation and others attempt
to portray more precise imaging.
In both cases position the speakers to the
sides and behind the listeners.
For more precise imaging, mount the
speakers at or just above ear height and
point them at the listening area. (figure 3)
Do not expect the imaging to the sides and
rear to be as precise as at the front.
Phantom images between the speakers are
fairly easy to create with sustained tones,
but fricative or percussive sounds can tend
to localise more at the speakers. It is also
difficult to get an ideal balance between
front and surround speakers for more than
one row of listeners.
For a more diffuse effect, mount the
speakers higher and point them along
either the rear or side wall. (figure 4)
2-Channel Audio (figure 5)
Mount the speakers so that the tweeters
are approximately at ear level.
As an initial guide:
Position the speakers and the centre of
the listening area approximately at the
corners of an equilateral triangle.
Keep the speakers at least 1.5m apart
to maintain left-right separation.
Keep the speaker baffles at least 0.5m
clear of walls.
Stray magnetic fields
The speaker drive units are magnetically
shielded such that the stray magnetic field
outside the boundaries of the cabinet,
except the front, is too low to cause
distortion of the television picture in the
vast majority of cases.
There are, however, some extremely
sensitive televisions – some that even have
to be adjusted according to their alignment
with the earth’s magnetic field. If you have
a problem, first degauss the television set
with the speaker in place. Some have a
button especially for this purpose. If not,
switch off the set at the mains for
